For effective bath lighting of any sort, it’s smart to pay attention to the CRI (color rendering index). A number of 100 is ideal but hard to find. Anything over 80 will allow people to see colors fairly accurately. Finally, don’t forget to specify the color temperature, expressed in degrees Kelvin (K). A 2,700K lamp is about the same warm yellow light as an incandescent bulb, and many clients prefer them. Jumping up to a 3,000K lamp makes a whiter light, still warm, that’s a good compromise. For residential use, 3,500K is about as cool a color as I’d recommend—it’s particularly good in closets, where you need accuracy for color matching when choosing clothing. Many clothing stores use 3,500K lighting for that reason.
How much light is needed in the bath? The answer depends on the person and the task they’re performing. For someone just waking up and shuffling in to the water closet, 10 footcandles (fc) might be plenty. After a shower, when it’s time to shave, 100fc is probably needed for better visibility.
Another great ambient light source in baths is indirect up-lighting, usually achieved with fluorescent or LED light strips on top of cabinets or a soffit. This is particularly soft, pleasant background illumination.
High-end hotels sometimes feature LED tape lighting under a vanity or a countertop edge for this purpose. In most of our higher-end work, we provide an electrical outlet behind the toilet for a bidet seat, and this is a perfect place to plug in one of these lights. Recently, several manufacturers have started offering LED lighting in the toilet seat for wayfinding.
